same problem here with win7 64bit and linux debian 32bit... except that i'm not using a switch but a bunch of cables. did you found any solution? anyone any idea? thanks !
maybe i should mention that linux is running on a notebook, windows on a desktop.
Nothing worked, despite much searching.
I connected some old POWERED speakers and voila.
Still can`t explain-WHY- but it now functions very well.
Thanks for all your interest and help.
